OK, the attached is a patch against 1.0.6 that adds
a generic IP packet debugging function for test purposes. Currently,
we use it only to to dump some general info about the protocol headers
in the ICMP packets with failed checksum. I dumped some packets
with it, so it appears to work. I assume it will catch only
packets damaged from network but if you are lucky you can
see even packets not related to LVS connections.
